The Gotham Archipelago

CNNMoney/Dow Jones: Sources:Langone May Bid for Archipelago. Financier Kenneth Langone is mounting a rival bid to buy electronic trading platform Archipelago Holdings, a move rich in Wall Street politics that threatens to derail its proposed union with the New York Stock Exchange, according to people familiar with the matter.

I’ve added Archipelago Holdings contracts and Instinet Group contracts to the web site. NASDAQ contracts were already up.
